When processing memberships transactions in the NetCommunity plugin a prompt is normally displayed stating 'This transaction has unprocessed Profile Updates. Would you like to process them?'. This allows you to apply any changes the user made to their profile information. However, if the transaction displays an auto-match the same prompt is not displayed and the constituent linking window must be opened to have the information update.
We are currently evaluating this issue and will update this article when we have more information.
